node editor - pyflow

[saso]

I wrote the nodes after my investigation of the corona data sets, but the nodes are not only useful for this kind of data.
I see here a way to use external tables( in this first stage only simple csv files) as parameter sets for cad models...

Yes, I understand the idea and find it nice to see how flexible the system can be, but still I cannot ignore the feeling that it is maybe a bit too much too soon, that it would maybe be better to still focus a bit more on the more basic things and examples.

I guess node editor could be in the future merged in to the master and have a default basic set of nodes and then have in the "Addons manager" an additional tab for "Nodes" where the users could install additional node packages for more specific needs and that most of this node packages would be created by the wider community.

If some one have any Idea of what can I do to solve it.

You still have to register the package see:
https://forum.freecadweb.org/viewtopic. ... 40#p360762

One more remark:
I still have to publish the new packages cypher and www:

*add documentation
* refine code
*tests and make the nodes robust.

this will happen next days.

Thank a lot for your help.
After register the package I was able to see the package list.
Sadly when I try to do things with node I get some message errors after click on "create all Nodes for Tests".

I also try https://www.youtube.com/watch?v=0RjuXiqfQZo
What it look like to be the "node editor hello world".
I got some errors
I fix few of by installing dependency
python3-tk
python3-scipy

Now when I insert dragger node and click on start I got this message

At this step I can't find what is missing. Is there something more I should install ?
Once again thanks a lot for your work and help.

Uups,
There are files not checked in.
I will fix it.

Ok thanks,
No worries.
Let us know when you're update the master branch.

Maybe after a few group of users report you successful installation you can publish a release ?

Or at least it would be good to have a git tag with a version number off a stable branch or a release version.
It's written on the readme v0.22 did you have some version tag on your local machine ?

I am sure that how to get this running is somewhere in the 24 pages (so far) of this thread but could you add a link to that to the first post so it is easy to find for those (like me) who just want to give it a try?

BSpline Surfaces are not developable.
To get a paper model of a terrain I split the surface in stripes, convert them to ruled surfaces and approximate the result by a chain of trinagles.
The result can be printed out, cutted and composed to a 3D paper model.
The last steps can be done by children too.
the surface:

the approximation CAD model

the drawings


cutted



The first paper model. I will repeat it with thick cardboard to get it more stable.
